u={"admin": "123456", "fly": "abc123", "jack": "jack@123", "mary": "you87"}

for i in range(3):
    x,y=map(str,input().split())
    if x in u and y == u[x]:
        print('登录成功')
        break
    elif i == 2:
        print('登录失败')
    elif x in u and y != u[x]:
        print('密码错误')
    else:
        print('输入错误，请重新输入')
